Faucet “washer” replacement?

Photomom

This plastic thing that is supposed to seal between the faucet and the counter has gotten damaged. Any ideas what to use for a replacement? Just glob some caulk in there? I’ve loosened the nut underneath and can raise the faucet about a quarter inch. Will replace the faucet at some point but was not planning to do it now.

I assume this seal is just to keep splash water from dribbling down into the cabinet below the sink.

Caulk would probably work, but a little plumber's putty might be easier and less messy (especially if you plan to remove it later). If you can raise the faucet up 1/4" you can work a little snake of it into a ring around the edge. It will squash down when you tighten things back up, and the excess can be easily trimmed.

The putty sounds like it will work, thanks!

Plumbers putty is not for plastics. Won't stick. Just take the old one to Ace and get another o ring to put in the groove. Might need to disconnect the water lines and fully remove the faucet to do it.

It looks like the water lines are crimped on and would have to be cut, so I need a solution that doesn’t require removing the faucet,

They should just unscrew under the sink.

@Photomom, here is a post where @HR_Taly replaced the original T@B faucet and describes how it was removed. https://tab-rv.vanillaforums.com/discussion/6335/kitchen-faucet-replacement-t-b-320-s

Given HR_Taly's experience with those cheesy connectors, I wouldn't be inclined to stress them much unless you are prepared to replace the entire faucet on the spot. (Which, given HR_Taly's excellent instructional write up, might be your best choice!)

I think you can get plumber's putty indicated for use with plastic. As RollingBnB indicated, it may not stick well. Another option might be to get a sheet of gasket material and cut yourself a nice wide washer to fit under there. You'd have to slice it to fit it around the pipe, but--since this is really only for splash and maybe vibration protection--it doesn't need to be a 100% perfect seal.

Back to your original idea--silicone caulk would also do the job nicely, but might be difficult to remove and clean up when you decide to change the faucet out for real.
